One of several managers the brothers hired over the years to oversee the day-to-day operations of the roadhouse was Charles A. Semlin, later the Premier of B.C.

Clement became the postmaster for the area in 1865 and then the district magistrate in 1867. When he was appointed Lieutenant-Governor of B.C., in 1885 his brother took responsibility for the ranch's operation.

Clement married Charlotte Pemberton in 1870, and raised five children; Henry married Mary Josephine Eyre, and raised four children. Henry died in 1892, and Clement in 1910.

Clements remains are buried in the family graveyard at Ashcroft Manor. The last of the Cornwall family to live in Ashcroft Manor was Henry Cornwall's great granddaughter Vashti (Parker) Fisk who purchased the manor property in 1972. The Fisks approached several government agencies to assist in restoration of the deteriorating house to no avail.

In 1981 Tom and Susan Saunders purchased the property and today the restored roadhouse is a restaurant and tea house where refreshments are served (p100 and 101, B.Patenaude:1995).
